Road engineering roadbed compactness detection equipment

The utility model discloses highway engineering roadbed compactness detection equipment, and particularly relates to the technical field of highway engineering, the highway engineering roadbed compactness detection equipment comprises a dust cover, a supporting rod is fixedly installed in the middle of the upper end of the dust cover, a movable cavity is formed in the supporting rod, and a hydraulic telescopic rod is fixedly installed on the top wall of the movable cavity; and an equipment cylinder is fixedly mounted at the output end of the hydraulic telescopic rod. According to the road engineering roadbed compactness detection equipment, sampling can be rapidly carried out through mutual cooperation of the hydraulic telescopic rod, the motor, the drill rod, the auger and the sampling pipe, the labor intensity of workers is reduced, meanwhile, soil is stored in the sampling pipe to be collected in the drilling and sampling process, scattering of the soil on the ground cannot be caused, and the detection eff
